A Methodological Approach to an Economic Analysis of the Beneficial Outcomes of Water Quality: Improvement from Sewage Treatment Plant Upgrading and Combined Sewer Overflow Controls

The purpose of this report is to determine the feasibility and usefulness of an economic analysis of the beneficial outcomes of water quality improvements that should result from upgrading sewage treatments plants (STPs) and from combined sewer overflow (CSO) controls. This report uses Boston Harbor, Boston, Massachusetts, to serve as a case study which demonstrates the application of a variety of benefit estimation techniques in order to develop a range of benefit values associated with the uses of the Harbor which would be affected by the various pollution control treatment alternatives. It contains pertinent data and computation to demonstrate the application of the techniques. This report may also serve as an Appendix to the EPA's Marine CSO Handbook, which states can use as an example of how to perform benefit analysis. Where feasible, the study provided dollar estimates of the economic benefits of the treatment alternatives for the two primary benefit categories (recreation and commercial fishing) as well as for other relevant benefits.
The report includes 12 major sections and five appendices, as shown under File Description below:
